Title: Disazo dyestuffs and processes for their manufacture and use
IPC: C09B35/031
Filed: 1969-12-31
Abstract: 1291100 Disazo compounds CIBA-GEIGY AG 31 Dec 1969 [3 Jan 1969 11 June 1969] 63496/69 Heading C4P The invention comprises disazo dyes free from water-solubilizing groups of the formula wherein D represents the residue of a benzenoid diazo component or the residue of a coupling component; R represents an alkyl group having 1-4 carbon atoms, or a hydrogen atom; and B represents the residue of a coupling component free from acidic groups imparting solubility in water. Suitable coupling components that B and D may represent are those of the enol or aniline series or those having active or acidified hydrogen atoms, and heterocyclic coupling components. The dyes may be prepared by coupling the diazonium compound or a hydrazine derivative of an azobenzthiazolyl-2- amine of formula with a compound H-B. Alternatively an acylaminobenzthiazolyl-2-amine of formula in which Ac is an acyl residue is diazotized and coupled with a compound H-B, the acylamino group is hydrolysed and the resulting amino group diazotized and coupled with a compound H-D. The dyes may also be subsequently treated with alkylating agents if they contain quaternatable nitrogen atoms. The dyes of Formula I may be used for dyeing or printing many substrates, particularly polyester or acrylic fibres and polypropylene fibres modified with nickel.
Patent GB-644404-A (GB)
Abstract: 644,404. Cash registers. ERICSSONS KASSAREGISTER AKTIEBOLAG, L. M. Dec. 31, 1947, No. 35284. Convention date, Dec. 12, 1946. [Class 106 (i)] A cash register adapted for printing and issuing a voucher from a continuous strip or alternatively for printing on an inserted bill, is .characterized in. that the strip-feeding mechanism normally keeps the strip retracted from the printing position, so as to allow the insertion and printing of a bill, and retracts the strip after each voucher-printing operation to its normal position. If no bill has been placed in the machine, a feeler-operated arm 18 forms a fulcrum for a bar 14 so that, when a starting key 10 is depressed, this bar 14 is moved off its pivot pin 16 downwardly against a spring 17. A pin 21 in the bar 14 moves a slide 23 downwards until it is held by a spring latch 28, and the slide 23 moves a roller 33 on a lever 35 into the path of a cam 36 which then rocks, through the lever 35, a partially-toothed segment 42 so that a roller 43 thereon enters the path of a cam 44. The segment 42 is then rocked clockwise and its teeth engage and rotate a partiallytoothed wheel 41 fast to one of a pair of feed rollers 5, thereby feeding the voucher-strip 8 until its end is engaged by a second pair of feed rollers 6. Printing hammers 2, 4 are then operated to take impressions from amount typewheels 1 and a block 3 and the feed rollers 6 are rotated in known manner further to advance the voucher-strip, such feed being permitted by a flat on the lower feed roller 5. A knife 7 is then operated in known manner to sever the voucher, the print from the block 3 remaining on the strip to form part of the next voucher. Finally, the cam 44 permits restoration of the segment 42 by a spring 45. At the same time the rollers 6 are separated by known means to allow the voucher-strip to be withdrawn from the printing position. If, however, a bill is inserted on a table 9 prior to the depression of the starting key, a pivoted feeler 20 integral with the arm 18 is rocked counter-clockwise so that depression of the starting key 10 rocks the bar 14 ineffectively on its pivot 16. The voucher-strip thus remains free of the printing- mechanism during the ensuing operation.
Patent GB-687628-A (GB)
Abstract: 687,628. Temperature-responsive actuating elements. VAILLANT, H., [trading as VAILLANT KOMMANDIT-GES., J.] March 6, 1951, No. 5360/51. Class 64 (ii) [Also in Group XXIX] A thermally actuated valve of a pilot-flame safety device for a gas water-heater is operated by a bimetallic strip which is bent into a semi-circle and is rotatably connected at its ends to a stationary part and to the controlling member of the valve. The ends of the strip are bent around to form bearing eyes. The more expansible metal is on the outside of the eyes so that bushings inserted in the eyes are gripped more tightly on heating. In one form, Fig. 1, the ends of the strip 7 are also forked to receive the valve rod 4 which is attached to one end of the strip. In another form, Fig. 3, the strip 22, which is heated by a pilot burner 25 associated with a main burner .12, is connected at one end to the burner 12 and at the other end to a lever pivoted at 13 and actuating a valve 19. The arm 16 of the lever engages in a friction clamp 17 which permits the lever arm 14 to move and the bimetallic strip to be deformed even when the latter is heated or cooled beyond the temperature at which the arm 16 reaches the stop 26 or the valve 19 is closed. Initially, the valve 19 is opened by a tilting movement.

Title: Improvements In Or Relating to Autoclaves
IPC: A47J27/092
Filed: 1979-03-08
Abstract: An autoclave includes an open- mouthed pressure vessel body 11, a lid 10 for the pressure vessel, one or more bolts 12 for locking the lid in a position in which it closes the mouth of the pressure vessel 11, a thermocouple for detecting the temperature in the autoclave and locking mechanism for engaging one of the bolts to prevent withdrawal of that bolt whenever the temperature detected by the thermocouple is above a predetermined temperature.
